slic3r how to gcode only the surface ???

Hy guys.

I am currently visiting a friend who is running a robot company fabricating things for the German car industry.
Here we have a huge 7-axis robot which is out of use.

So within 2 days, we want to mount a dremel

18 mm T- HSS Fräser Schruppfräser 5 schneidig Zylinderschaft
and drill a 2 meter sculpture out of wood.

I have a reprap and am able to generate that gcode with slic3r.

What i need is just a long list of x,y,z coordinates..

I can write a program that somehow deletes all the inner
G1 X103.114 Y90.974 E1.32101
lines. But you might like to tell, how i simply can disable all input filling.

Setting fill-density to 0 is not enough, as slic3r still adds supporting inner filling when needed.
And always with the bottom- and top-layers.

I guess, there is a simply trick to get a gecode-file only containig the outer surface.

And yes, even better would be (x,alpha,z) triples :-)
This huge robot has a "print bed" that can be rotated 360°

The dremel will only move up and down (z-axis) and drill into the wood (x-axis)
Perhaps, there is even a slic3r setting for such a reprap.

Ideas welcome,

Okay, needed a newer slic3r version, than

perimeters: 1
Generate extra perimeters when needed: no
solid layers: top 0 , bottom 0
fill density : 0

does the job :-)


Only thing left is to generate gcode for a rotating print bed.
